Advanced Tickets = $35
Same Day = $40
70 = total tickets
x = number of advance day tickets sold
so (70-x) = same day tickets
------------------------------------------------------------
$2650 = $35(x) + $40(70-x)
2650 = 35x + 2800 - 40x
-2800+2650 = -5x
-150=--5x
x = 30; the number of advanced tickets
Therefore 70-30 = 40 day of ticktes
Check the answer:
2650 = 35*30 + 40*40
2650=1050+1600
2650=2650
